ABSTRACT

The cost of treated water makes most people in rural community’s to resort to readily available sources which are normally of low quality exposing them to waterborne diseases. Chemical coagulants like ammonium sulphate which used in treatment plant for purification process but the extensive use can cause problems and it is costlier and to overcome these problems it is necessary to increase the use of natural coagulants. There are different types of natural coagulants, among them one of the natural coagulant is Moringa oleifera. It is in this light that project is carrying out to confirm the effectiveness of powder extracted from mature dried Moringa oleifera seeds which is commonly available in most rural areas. Model turbid water was treated by coagulation, flocculation and sedimentation with Moringa oleifera seeds powder as a coagulant, using jar tests. The quality of water is analyzed and compared with that of the water with alum. Experiments were conducted at various dosages. To evaluate the antimicrobial activity and efficiency of a natural absorbent from Moringa oleifera seeds in treating water by physicochemical methods. Turbidity, pH, alkalinity, jar test, conductivity, chlorides and total coliform test was performed. The specific objectives is to establish the best dose of powder Moringa oleifera seeds that best removes different parameters from water and to compare between the Moringa seed powder and the selected commercial sold water treatment chemicals. M. Oleifera works as a coagulant due to the positive charge, water soluble proteins which bind with negatively charges particles allowing the formation of flocks to settle to the bottom or be removed by filtration sand and it is accepted that treatment with Moringa oleifera seed solution will remove 90-99% of impurities in water.
